I am seriously considering a diesel swap in my '98 Sport 4.0 aw4 up country. Who's done one? I am looking at a KJ 2.8l, iveco 4cyl, or maybe an isuzu 4cyl turbo diesel. Also has anyone stuck a manual transmission behind one of the KJ engines? I thought about a 4bt but it weighs too much and requires a lot of lift to fit.
